the defense between an earthquake's focus and its epicenter.

Answers

Answer: The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. The epicenter is the point on the surface above the focus, the place on the surface that would receive the most intense vibrations.

Explanation: Hope it helps <3

The focus is the point within the earth where seismic waves originate; it is centered on the part of the fault that has the greatest movement. The epicenter is on the earth's surface directly above the focus.

Team Kyoto and Team Copenhagen are engaged in a fierce game of Tug of War. Team Kyoto pulls to the left with a force of 5000N and Team Copenhagen pulls to the right with a force of 5000N. Explain what net force will be and in which way (if any) the rope will accelerate.


helpppp due in 20 mins no links pweysss

Answers

Answer:

net force will be 0N and the rope will not accelerate.

Explanation:

to calculate net force, you need to find the difference between the two forces, which would be 5000N - 5000N = 0N

since there is no net force, there is no movement of the rope.

There are millions of polar ice caps in the world and there are Millions of wildlife and organisms living on them. They can grow enormous up to 50,000 square kilometers. They take up 14.6 million km of the earth. They are getting smaller day by day and night by night. They are melting. At the rate that it is melting by 2035, the polar ice caps will be gone and all coastal cities will be flooded and destroyed. The polar ice caps would have been around for millions of years in the world's oldest architecture. There are so many animals that live under polar ice caps. Some animals are brown bears, polar bears, arctic foxes and wolves, whales, birds, fish, krill, penguins, etc. There are so many animals that stay alive on and under the ice caps. The environment is perfect for the animals and we are ruining it for those animals. The ecosystem under the icecaps is amazing. It is a great place for fish, krill, and aquatic organisms. It is a safe spot for small animals because the animals on top of the ice caps won't go into the water unless they have to because there are bigger predators in the water like leopard seals, killer whales, and big fish. More and more animals die every day because the ice caps are getting smaller and smaller There are big rivers that are flowing into the ocean from the ice caps. These Rivers are bad because they flood everywhere and it ruins animals' homes and shelters. It is also good because now the animals can drink and not have to worry about getting eaten by a leopard seal or a killer whale, but now the animals will overpopulate and be indeed for more food. Every day billions of tons of ice melt, and the ice caps have 90% of the freshwater on earth. The ice caps are breaking apart and big chunks of them are starting to fall into the water which isn't good because they are raising the sea level. They are not good to have in our ocean because the broken pieces take a long time to melt and those big chunks float and also hit boats or other ice caps that break apart them. It is not good to have thousands of ice caps scattered around the take up The only way we can slow down the process of melting is if we stop burning so much energy and use solar or electric power to do our daily tasks driving places and burning trash. Electric cars are great for the world but we need to find a better power source because it is hard to get so much electrical energy from the earth. Solar power is another way millions of people use solar power on their roofs of their houses so that the power that they receive from the sun is subtracted from their electrical bill. It is a great power source but it is not as effective because it requires an extremely strong energy source to power them. Luckily we have the sun and that helps out a bunch. Climate change also is a huge factor in the melting of the polar ice caps. When the climate changes everything has to adjust to that climate and the ice caps can't. Over the past 100 years, the climate has changed by 1.0o F. That is a lot. Even though it seems so small for the climate to change it takes a lot of burning fuel and waste. We cut and burn so much wood, metal, biofuel, trash, etc. We all do it even if you think you recycle some of it still is burned so try to reuse your trash as much as possible. When we reuse something it proves that something can be used twice rather than throwing it out without seeing what you could do with it. You can reuse anything like plastic water bottles, home depot buckets, plastic straws, fruit cups, and much more. Everything helps the environment and you should make a difference by going out of your way to do things for the environment. Picking up trash on the road, sidewalk, forest, buildings, or anywhere you can think of. When you do a small act of kindness you can feel better. You also help the ice caps from melting faster.
